--- Comment #2 from Joshua Clayton <stillcompiling at gmail.com> ---
In my case, a mailing-list filter hung, so I stopped akonadi, closed kmail.
kmail crashed on restart. Logging completely out is the only way to get it back
into a working state.

Another possible clue: when started from the command line, I get the following
warning:

me at my-pc:~$ kmail
QDBusConnection: session D-Bus connection created before QCoreApplication.
Application may misbehave.

Application: KMail (kmail), signal: Segmentation fault
